CATSUP-CAP.

Specification of Letters Patent.

Patented Feb. 1, 1921.

Application filed. December 22, 1919. Serial No. 346,579.

To all whom'z't may concern.-

Be it known that I, CHARLES HAMMER, a citizen of the Unitedstates,-residin at Queens, in the county of Queens and tate of New York, haveinvented certain new and useful Improvements in Catsup-Caps, of whichthe following is a specification.

This invention relates to closures for containers of various styles,particularly the form of caps employed with bottles having narrow necks.

"One of the objects of this invention is to provide a form of bottleclosure made from a blank bent to a cylindrical shape to form a bodywith one end closed by a disk; in which the body at its lapping end isprovided with holding means at the top and bottom only of the cylinder,with the lapping margins merely in contact without any means ofinterlock or interfold, the raw edges of'the blankends being merelydoubled back on themselves on the inside of the meeting ends, and out ofengagement, and which holding means for top and bottom portions of thelapping ends, will prevent relative sliding movement of one body endportion on the face of the other body end portion, in a directionparallel with the ends of the blank, especially during manufacture.

A further object of this invention is to arrange the lapping ends sothat their edges are merely doubled back inwardly between the lappingportions without engagement, to cause but three thicknesses of metal atthese lapping portions between the top and bottom; whereby thecorrugation of the body to produce screw threads will not resultin anugly bulge at such portion, as would result where an interfold orinterlock between doubled margins is employed.

In the accompanying drawings representing embodiments of my invention,Figure 1 shows the blank for the body member.

Fig. 2 shows the blank with end portions slightly bent over.

Fig. 3 is an edge view of the blank.

Fig. 4 shows the blank for a modification.

Fig. 5 shows the latter with the ends bent.

Fig. 6 is a vertical section through the closure.

Fig. '7 is a partial vertical section enlarged on the line 77 of Fig. 6.

Fig. 8 is an inside view enlarged of the top and bottom of the bodyblank before the end disk is applied.

Fig. 9 is a cross section on the line 9-9 of Fig. 8.

Fig. 10 is a cross section on the line 10-10 of Fig. 8.

Fig. 11 shows the finished closure in perspective.

In Fig. 1, I show a blank in the form of a strip 1 having one end bentover to form a channel 2, the end portions 3 and 4 of the bend beinginclined as shown. At the other end of the blank one corner portion 8 isremoved, and the two square corners 10 and 11 are bent down on-obhquelines on the outer face of the blank to form hooks 12 and 13, see Figs.2 and 3. It will be noticed that these hooks are in proximity to thelongitudinal edges of the blank, and extend in 0pposite directions. Theblank is then bent into the form of a cylinder with the face 14 outward,and the hooks 12 and 13 are caused to engage the inclined end portions 3and 4 of the channel 2 at the other end, as indicated in Fig. 9. Thejoint is now pressed strongly together, as indicated in Figs. 9 and 10,and the portion of the channel 2 between the hook portions 12 and 13will be bent tight against the face of the blank.

The end of the body thus formed into a cylinder, is closed by a disk 15,that is caused to interlock with the edge of the body by an interfoldedjoint of the well known form, such as set forth in U. S. patent to Kind,No. 321,822, of 1885. This is indicated in Figs. 6 and 11, and the hookportion 12, with the engaging portion of the channel 2, is located sothat it will be included in this interlock with the top 15.

At the lower margin of the closure the edge is bent outwardly to form abead or wired edge 16, and the hook 13, with the engaging portion of thechannel 2 is included in thiswired edge, as shown in Figs. 6 and 7.

The lower portion of the closuremay be provided with corrugationsextending around in the form of a screw thread 17, as shown. But thisthreaded portion terminates just above a short cylindrical portion 18adjacent the bead 16, and which is made of sufficlent in ternal diameterto pass over the screw threads on the bottle neck.

It will be understood that the placing of the hook portions that engagethe ends of the channel portion in the upper and lower bent edges of thebody, cause a secure fastening, and also serve to obscure the slightextra thickness caused thereby, also are free from the screw threadedportion.

In the process of manufacturing a cap of this character, the strip ofsheet metal, previously bent at one end to form a channel with obliqueends, and having at the other end a pair of hooks that extend oblique tothe transverse end of the blank in opposite directions, is first bentaround to a cylindrical form to bring the hook and tongue portionsslightly past each other as lapped. whereby the hooks are caused toenter into the bent-channel portion, and the cylindrical body is thenenlarged in diameter to tightly engage the hooks and channel. andfinally bumped by a plunger on the engaging portions, and the hooks andbent tongue portion are pressed fiat.

If the end portions were merely interlocked by a bent channel on eachbody end, they would have a sliding movement of one end portion on theother, and one edge might be advanced beyond the other, and

, when the end disk is inserted and interfolded, an irregular cap wouldresult. This difiiculty is overcome by means of my ohlique hookportions, that engage the oblique ends of the bent tongue, so that assoon as the hooks engage the tongue, this edgewise movement isabsolutely prevented.

These hook portions being at the top and bottom edges, will be includedin the bead at the open end, and also in the interfolding with the edgeof the top disk. By. this arrangement substantially the entire lappingend portions of the body member, between the top disk and the wiredlower edge, are free of all forms of interlocking or interfolding means,and the lapping end portions have merely the raw edges doubled overwithout engagement. Therefore, at no place, exceptthe two bent hooks, isthere four thicknesses of'metal, as would result from an interlocking orinterfolded joint, but only three thicknesses, between the top andbottom hook portions;

In Figs. 4 and 5, I show a slight modification in which the blank 20 hasin addition to the removed corner portion 21 an extension 22in the formof a tongue with notches 23 and 24 at the ends. This tongue 22 is bentback to form a double portion 24. see Fig. 5, extending between the benthook portions 26 and 27, that correspond to the hook portions 12 and 13.At the other end this blank has the bent tongue portion 28 correspondingto the bend 2. The construction of this cap is the same as the formdescribed, except that between the engaging hook portions the two rawedges of the blank are doubled inwardly, and would appear substantiallyas shown in the section of Fig. 9.

This application is a continuation in part of an application filed by meApril 23, 1919,

Serial Number 292,193.
